Homework Equations
The Attempt at a Solution
I made an x vs. t graph, a v vs. t graph, and an a vs. t graph.
My variable list is as follows:
x at time 0(initial location)=5m
x(location) at end time=0m
initial velocity= is unknown
Velocity at end=0m/s
time=is unknown
acceleration=-9.8m/s^2 (which is free fall)
